Question:
For Problem 9.162E, consider the boiler/ superheater. Find the exergy destruction and the second-law efficiency for the boiler-source setup.
Data from Problem 9.162E,
A Rankine cycle feeds 10 lbm/s ammonia at 300 psia, 280 F to the turbine, which has an extraction point at 125 psia. The condenser is at 0 F, and a closed FWH has an exit state (3) at the temperature of the condensing extraction flow and it also has a drip pump. The source for the boiler is at constant 350 F. Find the extraction flow rate and state 4 into the boiler.
